SIX Greenpeace women scaled Britain’s tallest building yesterday to protest at oil drilling in the Arctic

They fooled security at the 72-storey building shortly after 4am by using a ladder to clamber on to a ticket office at neighbouring London Bridge station, claiming they were working on a Thameslink rail project.

From there they used ropes and hooks to reach the Shard and began their 15-hour ascent to the summit.

They reached the top at 7pm but abandoned a planned attempt to unfurl a huge protest banner and instead flew a Greenpeace flag.

Then they began their descent. Last night the six were arrested on suspicion of aggravated trespass.

Their banner would have protested about oil giant Shell, whose UK headquarters is at nearby Waterloo.
